Abstract
En 中文
Most existing relation extraction methods only determine the relation type after identifying all entities, thus not fully modeling the interaction between relation-type recognition and entity mention detection. This article introduces a novel paradigm for relation extraction by treating relevant entities as parameters of relations and harnessing the strong expressive capabilities and acceleration advantages of quantum computing to address the relation extraction task. In this article, we develop a quantum hierarchical reinforcement learning approach to enhance the interaction between relation-type recognition and entity mention detection. The entire relation extraction process is broken down into a hierarchical structure of two layers of quantum reinforcement learning strategies dedicated to relation detection and entity extraction, demonstrating greater feasibility and expressiveness, especially when dealing with superimposed relations. Our proposed method outperforms existing approaches through experimental evaluations on commonly used public datasets, mainly showcasing its significant advantages in extracting superimposed relationships.
